<p>
          Boost.Asio's implementation can use <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">shared_ptr</span><span class="special">&lt;&gt;</span></code> and <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">weak_ptr</span><span class="special">&lt;&gt;</span></code> in preference to the Boost equivalents.
        </p>
<p>
          Support for the standard smart pointers is automatically enabled for <code class="literal">g++</code>
          4.3 and later, when the <code class="literal">-std=c++0x</code> or <code class="literal">-std=gnu++0x</code>
          compiler options are used, as well as for Microsoft Visual C++ 10. It may
          be disabled by defining <code class="computeroutput"><span class="identifier">BOOST_ASIO_DISABLE_STD_SHARED_PTR</span></code>,
          or explicitly enabled for other compilers by defining <code class="computeroutput"><span class="identifier">BOOST_ASIO_HAS_STD_SHARED_PTR</span></code>.
